The TEMPCAL2 two-point calibration service for Campbell Scientific thermistor-based products, previously offered on an as-requested basis, is now available as a standard line item. With this service, we test the thermistor-based product at high and low ends of a specified temperature range and provide an NIST-traceable calibration sheet that specifies the sensor’s response. The standard two-point calibration determines offsets at 30°C and 65°C with an uncertainty of ±0.05°C. If your application requires the calibration to be made at different temperature values, you can specify this when you request the service. Typically, the calibration service is requested when you order the sensor. If you would like the calibration service performed on a sensor you already own, you can return the sensor via a Return Material Authorization (RMA).
